Weight for custom Fields is a module built to set weight based on form id and field name. WFCF module will be useful when a form field is missed out to set the weight which cannot be changeable in the User Interface, Those non-changeable field weights can be configured here.

Some contrib /custom modules have custom fields appended to core forms where you cannot change the order of that field in that case you need write custom code to add weight to that field to change that field order. WFCF module will allows you to configure it in User Interface.
